RESULTS: Analysis 2 - Lab Scenario 1 pt2
Bishop Simplified Method of Analysis -Circular Failure Surface
-------------------------------------------------------------
Critical Failure Circle Search using Multiple Circle Generation Techniques
Factor of Safety for initial failure circle approximation: 3.20
There were: 53404 successful analyses from a total of 125D01 trial circles
71585 analyses terminated due to unacceptable geometry
12 analyses that failed to produce a result
Critical (minimum) Factor of Safety: 3.20
Negative normal stresses exist on the base of one or more slices -examine slice data and consult the GALENA Help utility
Test Factor is less than 0.2 lower limit for One oI more slices - examine slice data and consult the GALENA Help utility
